I have a web server I'm trying to make accessible, and although from the command line I get a connection by typing telnet localhost 80, it refuses nonlocal connections. The server is an AWS EC2 node, with a security group of quick-start-1 (22 and 80 are open), and the server has UFW installed, and I have already run ufw allow 80. ps wwaux | grep apache2 shows one root and six www-data processes.

What are the other possibilities for firewalls within the AWS Ubuntu Raring node, or between the node and my notebook? How can I disable the ?ghost firewall?, without compromising my system, so that it is available on port 80?

The system is available on port 22 and it has never given me trouble remotely accessing port 22.
